- Análise fatorial confirmatória do Extended Class Play numa amostra portuguesa de jovens adolescentesPublication . Correia, João Carlos Verdelho; Santos, António José; Freitas, Miguel da Costa Nunes de; Rosado, António Fernando; Rubin, KennethO Extended Class Play (ECP; Burgess, Rubin, Wojslawowicz, Rose-Krasnor, & Booth, 2003) procura avaliar, através dos relatos dos pares, a reputação social dos sujeitos. O objetivo deste trabalho é testar a estrutura hexafatorial recentemente proposta, averiguando igualmente a sua adequação para género e idade, numa amostra portuguesa de 465 adolescentes (230 raparigas). Uma Análise Fatorial Confi rmatória revelou que o modelo de seis fatores apresenta bons índices de ajustamento, de fi abilidade e validade e ainda boa adequação para gênero e idade. Estes resultados são consistentes com outros trabalhos, ao sugerir que o modelo hexafatorial do ECP apresenta capacidades psicométricas aceitáveis, constituindo-se como uma medida válida a utilizar na investigação sobre a reputação e o funcionamento sociais de adolescentes.
- Distinct profiles of relationships with mothers, fathers, and best friends and social‐behavioral functioning in early adolescence: A cross‐cultural studyPublication . Oh, Wonjung; Bowker, Julie C; Santos, António J.; Ribeiro, Olívia; de Melo Guedes, Maryse; Freitas, Miguel; Kim, Hyoun K.; Song, Seowon; Rubin, KennethAdolescents’ dyadic relationships are likely influenced by the cultural context within which they exist. This study applied a person-oriented approach to examine how perceived support and negativity were manifested across youths’ relationships with mothers, fathers, and best friends, simultaneously, and how distinct relationship profiles were linked to adaptive and maladaptive functioning (aggression, anxious-withdrawal, prosociality) within and across cultures. Participants resided in metropolitan areas of South Korea, the United States, and Portugal (10–14 years; N = 1,233). Latent profile analyses identified relationship profiles that were culturally common or specific. Additional findings highlighted commonality in the relations between a high-quality relationship profile and adaptive functioning, as well as cultural specificity in the buffering and differential effects of distinct relationship profiles on social-behavioral outcomes.
- Isolamento social e sentimento de solidão em jovens adolescentesPublication . Ferreira, Débora Sousa Simões; Santos, António José; Ribeiro, Olívia; Freitas, Miguel da Costa Nunes de; Correia, João Carlos Verdelho; Rubin, KennethOs estudos mostram a importância das relações de pares para um desenvolvimento saudável e harmonioso, principalmente no período da adolescência. Como tal, a problemática do isolamento social torna-se num domínio com redobrado interesse durante esta fase da vida dos jovens. São vários os estudos que associam o retraimento social de crianças e adolescentes a consequências ligadas a perturbações internalizadas, como por exemplo, a solidão. O presente estudo teve como objetivo verificar os sentimentos de solidão expressos por adolescentes isolados-retraídos e isolados-agressivos. Conjuntamente, também se pretendeu verificar se existiam e como se manifestavam as diferenças em função do sexo relativamente a esse sentimento quer para os adolescentes isolados-retraídos, quer para os isolados-agressivos. Participaram neste estudo 900 jovens adolescentes (446 do sexo feminino), com idades compreendidas entre os 12 e 15 anos, provenientes de duas escolas da região da grande Lisboa. Os instrumentos de recolha de dados utilizados foram o ECP (Extended Class Play) e RPQ (Relational Provision Loneliness Questionnaire). A análise multivariada das dimensões do RPQ em função do Grupo (controle, isolados-retraídos e isolados-agressivos) e Sexo revelou efeitos principais multivariados para ambos os fatores. Estes resultados evidenciaram um menor nível de Integração com os Pares nos adolescentes isolados-retraídos, comparativamente com os do grupo de controlo. Relativamente á Intimidade com os Pares verificou-se que os jovens isolados-retraídos apresentam níveis significativamente inferiores de intimidade por comparação com os do grupo de controlo. Considerando as diferenças em função do
- Loneliness and social functioning in adolescent peer victimizationPublication . Almeida, Telma Sousa; Ribeiro, Olívia; Freitas, Miguel; Rubin, Kenneth; Santos, António J.Interpersonal adversity such as peer victimization has been shown to have complex associations with other socio-emotional difficulties, particularly during adolescence. We used a multidimensional peer nomination measure on a sample of 440 (52% girls) 11- to 17-year-old (M = 13.14 years, SD = 1.26) Portuguese youths to identify three groups, classified by peers as (1) victimized adolescents who showed anxious withdrawn behaviors in the context of the peer group (n = 111), (2) victimized adolescents who did not exhibit anxious withdrawn behaviors (n = 104), and (3) non-victimized adolescents (n = 225). We compared these groups on their peer-reported social functioning and on their self-reported feelings of social and emotional loneliness (with peers and family). Anxiously withdrawn victims were viewed by peers as more excluded, less aggressive, less prosocial, and less popular than non-withdrawn victims and non-victims. Non-anxiously withdrawn victims were considered more excluded than non-victims, and more aggressive than both anxiously withdrawn victims and non-victims. Finally, anxiously withdrawn victims reported feeling less integrated and intimate with their peers than non-withdrawn victims and non-victims, which is indicative of greater feelings of social and emotional loneliness at school. Youths in the current study did not report feeling lonely in their family environment. Our findings thus provide further evidence that victimized youths constitute a heterogeneous group, which differ in the way they behave toward their peers and experience loneliness.
- Loneliness in adolescence: Confirmatory factor analysis of the relational provisions loneliness questionnaire (RPLQ) in a Portuguese samplePublication . Ribeiro, Olívia; Santos, António José; Freitas, Miguel; Rosado, António Fernando; Rubin, KennethThe present study assesses the factor structure, psychometric adequacy, and invariance across sex and age of the Relational Provisions Loneliness Questionnaire (RPLQ). Discriminant validity with an external criterion was also tested. In a sample of Portuguese adolescents, from 7th to 9th grade (N ¼ 817), Confirmatory Factor Analyses (CFA) were conducted to test a four-factor model of loneliness (lack of integration and/or intimacy in peer group and/or family). Results evidenced empirical support for the structure of the RPLQ loneliness scale, which fitted very well the proposed model, and provided adequate fit to the Portuguese data. There was substantial support for the construct validity (factorial, convergent, and discriminant) and reliability of the RPLQ. Measurement invariance (configural, metric, and scalar) was established across sex and age. Finally, it was assured discriminant validity, provided by the contrast with the social functioning dimensions in peer group. Overall, our findings support the conceptualization of loneliness in adolescence by peer- and family-related loneliness through lack of integration and intimacy. In a single instrument, the RPLQ loneliness scale combines measures of four important aspects of adolescents’ social life. This seems to be an adequate instrument to be used in the study of adolescents’ loneliness, in its different forms and across relational contexts
- Loneliness profiles in adolescence: Associations with sex and social adjustment to the peer groupPublication . Ribeiro, Olívia; Freitas, Miguel; Rubin, Kenneth; Santos, António J.Loneliness is a complex feeling associated with socio-emotional adjustment difficulties, particularly during adolescence. Such construct is often treated as unidimensional rather than multidimensional, moreover, studies consisting of both peer and family contexts, are very scarce. Adopting a multidimensional and person-centered approach, our study aimed to identify distinct clusters of adolescents with similar patterns of social and emotional loneliness with peers and family and to examine their differences in peer reported social adjustment, controlling for sex. Self-report and peer nomination data were collected from 691 participants (48.36% boys) aged between 11 and 16 years (M = 12.95, SD = 1.15). After controlling for age and preference for solitude, results revealed four clusters with specific configurations of loneliness forms and with different associations with positive or negative features of social adjustment to peer group. Two clusters exhibited adaptive profiles (lower vulnerability to maladjustment): less-lonely, and family-related loneliness profile, in which adolescents were viewed by peers as exhibiting more prosocial behaviors. The other two clusters displayed maladaptive profiles (higher vulnerability to maladjustment): more-lonely, and peer-related loneliness profile, in which adolescents were more likely viewed by their peers as socially withdrawn, peer-excluded, and peer-victimized. Additionally, our results revealed sex differences, with girls in the more-lonely profile showing significant higher social loneliness related to peer group, and higher social and emotional loneliness in family context. Our results highlight the importance of recognizing different forms of loneliness given the differences in adjustment to social contexts observed, shedding further light on this complex construct
- Multidimensional Factor Structure of the Modified Child Rearing Practices Report Questionnaire (CRPR-Q) in a sample of Portuguese mothers : a bifactor approachPublication . Ribeiro, Olívia; Guedes, Maryse; Veríssimo, Manuela; Rubin, Kenneth; Santos, António J.Abstract: Parental attitudes toward child socialization influence their child-rearing practices, the quality of parent-child relationships, and children’s developmental outcomes. The Modified Child Rearing Practices Questionnaire (CRPR-Q) has been widely used to assess parenting practices across children’s development. However, the few studies investigating its two-factorial structure (nurturance and restrictiveness) have shown inconsistent findings and have not explored measurement invariance across children’s sex and age groups. The aims of this study were to (1) further investigate the factorial structure of the CRPR-Q, by using bifactor solutions (b-confirmatory factor analysis [B-CFA] and b-exploratory structural equation modeling [B-ESEM]) and (2) examine the measurement invariance of CRPR-Q across children’s sex and age groups. A community sample of 589 Portuguese mothers of children aged 3 to 15 years completed the CRPR-Q. Our findings revealed that the B-ESEM model best fit the data. A clear differentiation between the two a priori factors (nurturance and restrictiveness) was found. However, our findings suggest the need to control for content specificity and rely on a broader perspective regarding the nurturance factor. Measurement invariance was observed across children’s sex but not across children’s age groups. These findings contribute to a more in-depth understanding of the underlying relationships among the CRPR-Q items.
- Perceções das famílias portuguesas acerca do impacto da participação no turtle programPublication . Guedes, Maryse; Matos, Inês; Almeida, Telma Sousa; Freitas, Miguel; Alves, Stephanie; Santos, António J.; Verissimo, Manuela; Chronis-Tuscano, Andrea; Rubin, Kenneth
- Perceções dos psicólogos portugueses acerca da aceitabilidade de uma intervenção dirigida a crianças inibidas em idade pré-escolarPublication . Guedes, Maryse; Alves, Stephanie; Santos, António J.; Verissimo, Manuela; Tuscano, Andrea Chronis; Danko, Christina; Rubin, KennethHigh and stable behavioral inhibition (BI) during early childhood have been associated with an increased risk of later anxiety disorders and peer difficulties. Developing evidence-based early interventions to prevent these unhealthy developmental trajectories has become a major focus of interest. However, these interventions are not yet available in Europe. This study aimed to explore the perceptions of Portuguese psychologists about the acceptability of the child component of the Turtle Program, before its dissemination in Portugal. Eighteen psychologists were distributed into three focus groups. Each group was moderated by a trained psychologist, using a semi-structured interview guide. The thematic analysis revealed that Portuguese psychologists acknowledged that the intervention needs to go beyond social skills training and enhance children’s positive self-perceptions. Overall, psychologists perceived the structure, contents, activities, and materials of the intervention to be acceptable. However, participants recommended minor modifications to strengthen the connection with naturalistic contexts, broaden the focus on emotional expressiveness and social interaction, and introduce creative activities and materials. These findings are consistent with previous research with LatinX practitioners, who typically agree with the acceptability of evidence-based child intervention principles and only report the need to introduce minor changes related to the way how interventions are delivered to children.
- Perceived attachment security to parents and peer victimization: Does adolescent's aggressive behaviour make a difference?Publication . Guedes, Maryse; Santos, António José; Ribeiro, Olívia; Freitas, Miguel da Costa Nunes de; Rubin, Kenneth; Veríssimo, ManuelaPeer victimization is one of the most prominent problems during adolescence. Research has distinguished aggressive and non-aggressive victims; however, there are still significant drawbacks in understanding the social and family functioning of these different groups of victimized adolescents. This study aimed to compare social behavior and perceived attachment security to parents of Portuguese adolescents, classified as aggressive victims, non-aggressive victims and non-victims. The sample consisted of 222 adolescents (115 boys, 107 girls) who completed the Kerns Security Scale and the Extended Class Play, to assess perceived attachment security and social behavior, respectively. Controlling for age and sex, aggressive victims and non-aggressive victims differed in anxious withdrawal but shared a similar profile in peer exclusion and prosocial behavior. Only aggressive victims reported lower attachment security to mother and father when compared to non-victims. These findings underline that victimized adolescents constitute a heterogeneous group in terms of their social and family functioning.
